Connectivity Unveiled: The Comprehensive and Pragmatic Design of Altair G1.1

Navigating the rear panel of the Auralic Altair G1.1 unveils a connectivity landscape meticulously designed to balance comprehensiveness with pragmatic functionality. This streaming DAC, priced at around 3,000 euros, seamlessly integrates into audio setups, providing essential connections while remaining practical in its approach.

High-quality RCA and antenna sockets adorn the rear panel, catering to analog and digital connectivity needs. The absence of an HDMI eARC port is notable, but the inclusion of Toslink offers an alternative avenue for connecting to a TV. The Altair G1.1’s commitment to versatility lies in its limitation to the most crucial connection types for digital and analog interfaces, including XLR, shared in this echelon of audio devices.

Auralic’s proprietary design features shine in the Altair’s connectivity array. The USB port, surpassing the conventional asynchronous connection, intricately cuts off the USB’s native 5V connection. Instead, it harnesses power via the high-quality internal “Purer-Power” linear power supply. Furthermore, including a temperature-controlled clock with a remarkable 72 fs (femtoseconds) accuracy ensures a clean power supply, enhancing overall connectivity precision.

While the Altair G1.1 may lack some of the specialized features in top-tier models, such as specific decoupling device feet, it compensates with a balanced selection of ports. It focuses on delivering essential, high-quality connections. This thoughtful connectivity design positions the Altair G1.1 as a pragmatic choice for audiophiles seeking to integrate their digital and analog audio sources seamlessly.

Operating Concept Unveiled: The Intuitive and Diverse Interface of Altair G1.1

The operating concept of the Auralic Altair G1.1 beckons users into a realm where intuitive control and diverse functionality converge. This streaming DAC, priced at approximately 3,000 euros, invites audiophiles to easily navigate its features, blending traditional control mechanisms with modern conveniences.

The device’s clear front panel provides an initial glimpse into Auralic’s operating philosophy. Controlled through a tactile rotary and push mechanism, the Altair’s interface utilizes symbols and menus displayed on a high-resolution color screen, surpassing 300 pixels per inch. The absence of touch controls, a departure from contemporary trends, speaks to Auralic’s commitment to a classic yet accessible approach.

The sophisticated Lightning DS app, an in-house Auralic creation, is a powerful controller for the Altair G1.1. While designed primarily for Apple users, this app streamlines device control and configuration, seamlessly integrating with popular streaming services such as Qobuz, Amazon, Tidal, KKBOX, NetEase, Highresaudio, and Internet radio via TuneIn. The Altair’s role as a music server is also underscored as the Lightning DS app effortlessly searches and organizes data storage devices connected to the device or on the network.

However, the app’s exclusivity to iOS/iPadOS may limit its accessibility. Auralic addresses this by offering an extensive setup via the web interface, allowing users to input Altair’s IP address into a browser’s URL bar. Alternatively, the device supports OpenHome-compatible apps like BubbleUPnP and Kazoo via UPnP. As an added convenience, the Altair is Roon Ready, catering to users of this popular music playback software.

Despite the small font size in the system menu, a commonality across Auralic components, the Altair G1.1’s operating concept impresses with its adaptability and diverse control options. This thoughtful design ensures users can tailor their experience based on individual preferences and seamlessly integrate the Altair into their preferred audio setup.

Addressing Imperfections: Critiques and Firmware Updates for Altair G1.1

While the Auralic Altair G1.1 stands as a beacon of audio excellence, the discerning audiophile may encounter a few imperfections, meticulously acknowledged by the manufacturer. A closer examination reveals these critiques, accompanied by Auralic’s commitment to continuous improvement through firmware updates.

Firstly, an occasional crackling sound during changes in sampling frequency has been identified. This subtle yet noticeable artifact, arising during transitions like the shift from 44.1 kHz to 48 kHz, prompted Auralic to confirm awareness of the issue and a promise of resolution in forthcoming firmware updates. As of the latest version (9.4), a switchable option called “Output Protection” has been introduced in the DAC setup, effectively addressing the crackling issue.

Secondly, the behavior of the Altair G1.1 when headphones are plugged in raises a point of critique. Ordinarily, one might expect the rear outputs to mute automatically. However, the Altair continues to allow the speakers to play concurrently. Auralic acknowledges this, and users are hopeful for a software enhancement in future updates to better align with user expectations.

Lastly, the Altair G1.1 lacks a conventional standby mode, offering only a “sleep mode.” While this mode keeps the network active, allowing the device to function as a server, its minimal power reduction (from around 14 W to 12 W) might not be sufficient for those aiming to minimize power consumption. Auralic recommends switching off the device if not used as a server for extended periods. The absence of a swift standby mode might inconvenience users seeking rapid reactivation, considering the Altair takes about one and a half minutes to boot up from a complete shutdown.

Auralic demonstrates a commendable commitment to addressing user feedback through firmware updates, ensuring the Altair G1.1 evolves and refines its performance over time. These critiques, though notable, are met with a proactive approach to enhancing the user experience and maintaining the brand’s reputation for excellence in the high-end audio sphere.
